If pistons were taller using the same bore and stroke you would have higher compression but less cc's.
1998cc and 86mm*86mm seems to be consistent throughout all 3s-* motors. -------------------- Mike W

QUOTE (delusionz @ Apr 23, 2011 - 9:13 AM)  If pistons were taller using the same bore and stroke you would have higher compression but less cc's. 1998cc and 86mm*86mm seems to be consistent throughout all 3s-* motors. the bore and stroke is what determines the cc's. the volume between the top of the piston at TDC and head have nothing to do with it. you can verify it by doing this: π * [(8.6cm/2)^2] * 8.6cm * 4 cylinders = 1998 cc's taller pistons (or longer rods) will just shift the stroke closer to the head resulting in higher compression but won't affect its cc's. -------------------- -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- |
